POURING POT USED IN CONNECTION WITH HQT-TOP FEEDERS.

- Application filed December 29, 1923. Serial No. 683,497.

To all whom 2'25 may concern:

Be it known that BLOOMFIELD H. HOWARD and ERNEST J. TURNER, citizens of the United States, residing, respectively, at

WVashington, District of Columbia, and

Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Pouring Pots used in Connection with Hot-Top Feeders, of which the following fication.

Our invention relates to improvements in pouring pots used in connection with hot top feeders. V

The object of our invention is to provide a pouring pot with means for supporting it on the upper end of the mold above the feeder or hot top so that the ouring operation into the feeder canrea weight of the pot thus lessening the liability ing the pouring operation;

Another object of our invention is to provide a pouring pot which will function with the feeder in preventing" seams and holes and also reduce segregation to a minimum.

Another object of our invention'is to provide a pouring 'pot adapted to be used in connection with any form of hot top feeders suchas shown in our numerous patents and at the same time obtain the above mentioned,

results.

A further object of our provide a simple, cheap and effective arrangement of this character in which the pouring pot can be readily placed in position or removed and provide certain details of structure and combination of parts hereinafter more fully set forth In the accompanying drawings,

Figure 13 is a vertical sectional view of the upper end of the ingot mold showing our improved shoulder feeder and showing a modi ed form of pouring pot and the support therefor.

Referring now to the drawings and particularly to Figure 1, 1 represents the ingot mold which as'shown is a circular form and having the hot top feeder supported at'its i1 per end by means of the ribs 3 all of w ieh is well understood and while we have shown this specific form of hot top feeder it will be understood that our invention is 'adapted to be used on any mold where the feeder extends above the upper end hot top thereon Resting upon 'theupper .edge 4 of the mold are the feet 5 carried by the standards 6 which extend upwardly along the outer periphery of the feeder and havetheir upper -ends turned inwardly as indicated at 6' and which have secured to their lower faces the frame 7. This frame as shown is made of sections riveted together and adapted to hold the standards together all of which form a frame adapted to slip over the upper end of the feeder.

The pouring pot 8 is of a cylindrical formhaving its lower end provided with an inwardly extending flange 9 which rests upon the inwardly turned ends 6' of the standards and whereby the pouring pot is supported ill above the hot top feeder in its proper position, yet the weight of the pouring pot is taken off the upper end of the hot top feeder as clearly shown in Figure 2 of the draw ings. The pouring pot is provided on opposite sides with lugs 10 by means of whichv it can be placed on and removed from the mold all of which is well understood in the art. The pouring pot is provided with a lining 11 of refractory material which rests upon the upper face of the flange 9, sa d flange extending inwardly beyond the said lining. Resting upon the flange 9 on the inside of the lining 11 is the pouring plate 12. This plate 12 is provided with a series.

of openings 13 therein, whereby the metal passes from the pouring pot into the feeder insmall streams.

In Figure 1 the mold l and the pouring pot supporting means 14 are constructed the same as that shown in Figures 1, 2, 3 and 4: of the drawings. The pouring pot 15 in this form is provided with a narrow inwardly extending flange 16 adapted to sup port the refractory lining 17 and the lower end of said lining is drawn inwardly forming the beveled wall 18. The pouring plate 19-is rovided with a beveled outer edge 20 where y the pouring plate is supported in the pot by the refractory lining.

In Figures 8 and 9 the pouring pot supporting means comprises a plate 20 of the shape to correspond to that of the feederand extends outwardly beyond the outer periphery thereof and is provi-dedwith a series of legs 21 adapted to rest upon .the upper end of themold 1. The ouring pot'22 rests upon the plate 20 as 0 early shown in Figure 9 of the drawings. In this form the pouring pot 22 is constructed exactly like that shown in Figure 4 of the drawings.

In the modification shown in Figure 10 of the drawings the pouring pot supporting means is a plate 23 having legs 24 supported in the same manner-as that shown in Figure 9.- The outer. edge of the plate 23 is turned upwardly forming an annular flange 25 adapted to engage the outer periphery of the pouring pot 26. In this form the pouringpot is made of a greater diameter than that of the feeder so as to provide for the flange 25 on the outside of the supporting legs.

In Figures 11 and 12 in order to support the pouring pot we have provided two strips of metal 26 and 27 having the downwardlyextending portions 28 and 29 which extend down along the outer wall of the feeder 3O and'are provided at the lower ends with the feet 31 and 32 which rest upon the upper end of the mold 1. In this form the pouring pot 32 rests upon the strips 26 and 27 which are supported thereby above the feeder. In this form the pouring pot is exactly like that shown in Figure 9.

In Figure 13 we have shown a metal plate 33 of shape. approximately thatiof thesupper edge of the feeder 34 and resting thereon. This form of support is more ,particularly adapted for feeders-in which theupper ends are provided with large annular flange for supporting the same in the upper end of the mold. In this form the pouring pct 35 is constructed like that shown in Figure 12 except that the pouring plate 36 is slightly conical, extending a slightdistance into .the.

upper end of the feeder, this plate 36 like the pouring plates of the other forms. is

provided with a series of openings 37 preferably conical is shaped with the larger opening within the pouring pot. 7
